❮ Canvas Reference

Example

Draw a cubic Bézier curve:

JavaScript:

const canvas = document.getElementById("myCanvas");
const ctx = canvas.getContext("2d");

ctx.beginPath();
ctx.moveTo(20, 20);
ctx.bezierCurveTo(20, 100, 200, 100, 200, 20);
ctx.stroke();

Description

The bezierCurveTo() method adds a curve to the path by using the control points that represent a cubic Bézier curve.

Use the stroke() or fill() method to draw the path.

A cubic bezier curve requires three points. The first two points are control points that are used in the cubic Bézier calculation and the last point is the ending point for the curve.  The starting point for the curve is the last point in the current path. If a path does not exist, use the beginPath() and moveTo() methods to define a starting point.

A cubic bezier curve

Start point: moveTo(20, 20)

Control point 1: bezierCurveTo(20, 100, 200, 100, 200, 20)

Control point 2: bezierCurveTo(20, 100, 200, 100, 200, 20)

End point: bezierCurveTo(20, 100, 200, 100, 200, 20)

Note

The quadraticCurveTo() Method has one control point instead of two.
